Filter by:The investigators will study 500 patients with any indication for 24-hours Ambulatory Blood Pressure Monitoring (ABPM). In this study will compare Blood Pressure measurements with an original automatic device every 5 minutes during 20 minutes while the subject waits room for appointment, against ABPM results.
The purpose of this study is to determine an effective teaching strategy for Physical Therapy students in a Doctor of Physical Therapy (DPT) program that will produce consistent and accurate measuring of patient BP readings in the healthcare clinic according to the guidelines established by the AHA.
Collect continuous systolic and diastolic blood pressure values and waveforms as recorded by an arterial line catheter and by non-invasive blood pressure (NIBP) and to collect Photoplethysmogram Pulse Oximetry (PPG) waveform in order to optimize the Sensifree algorithm.
The purpose of this study is to evaluate methods to modify blood pressure in humans and measure the effectiveness of such methods. A secondary outcome is to evaluate the performance of an investigational continuous non-invasive blood pressure (cNIBP) device created by Sensifree. The tests will per performed in non-hospitalized subjects under varied controlled conditions that include resting blood pressure and non-pharmacologically induced blood pressure changes.
The purpose of this study is to compare blood pressure values (systolic, diastolic, mean arterial pressure) and waveform as recorded by a radial arterial line catheter to the waveform and values as calculated by the Sensifree's algorithm from a PPG sensor from a variety group of patients during elective surgeries.
The purpose of the protocol is to compare Sensifree Alpha sensor signal morphology, measured at the radial artery, to an invasive arterial line pressure signal and the oxygen saturation as read by a pulse oximeter. The study will be split into two phases: the first phase will collect data for morphology analysis and algorithm development, the second phase will compare device performance to the reference invasive blood pressures. A secondary objective is to evaluate signal morphology changes due to changes in subject arm position.
Currently, BP is measured using an inflatable cuff wrapped around the patient's upper arm. This can be set to inflate every minute, but measurement may fail due to patient movement or shivering. Failed measurement occurs in up to 38% of patients. This study aims to determine how the Nexfin device - which measures BP using a cuff wrapped around a finger - compares to standard BP measurement.
